(12 pts.) A new diet has been developed for raising beef cows. Two random samples of size fifteen are independently selected, and one is given the new diet and the other is given the standard
diet. After 18 weeks, the weight gain was measured, and it was found that x1 = 35 with s1 = 8 and x2 = 26 with s2 = 6. Let μ1 and μ2 represent the mean weight gain we would observe for the entire
population of beef cows when on, respectively, a new diet and a standard diet. Assume that two- sample t procedures are safe to use.
(a) Test the following hypotheses using α=0.05 :
Ho:μ1=μ2,Ha:μ1>μ2
(b) Calculate 95% confidence interval for μ1 – μ2

A new drug has been developed to treat a condition, and it is
alleged to be more effective than traditional treatment. An
experiment will be conducted to test whether the claim is true. To
perform the hypothesis test, a 99% confidence level is selected for
the hypothesis test. The new drug will be administered to a sample
of 200 individuals with the condition, selected at random. Another
300 individuals are randomly selected to receive the traditional
treatment.
Of the 200...

A terrible new virus has been discovered amongst beef-cattle in
Southern Alberta. It is estimated that
44%
of all beef-cattle are infected with this virus. A team of
veterinarians have developed a simple test. Indications are that
this test will show a positive result - indicating the beef-cow
being tested has the virus - with a probability of
0.950.95.
Unfortunately, this test has a false-positive probability
of
0.060.06.
(a) A beef-cow in Southern Alberta was randomly chosen and
given this...

12. An agricultural research company has developed two new types
of soy bean seeds, call them "seed A" and "seed B". A study is
conducted to determine which will produce a higher mean yield. To
test the two types of seed, 20 similar plots of land were randomly
placed into one of two groups. One group of ten plots was planted
with "seed A", while the other ten plots were planted with "seed
B". The yield of each field, in...

A new fertilizer has been developed to increase the yield on
crops, and the makers of the fertilizer want to better understand
which of the two blends of this fertilizer are most effective for
wheat, corn, and soy beans crops. They test each of the two blends
on one sample of each of the three types of crops.

A new drug has been developed to treat a particular condition,
and it is alleged to be more effective than traditional treatment.
An experiment will be conducted to test whether the claim is true.
To perform the hypothesis test, a 95% confidence level is selected
for the hypothesis test. The new drug will be administered to a
sample of 200 individuals with the condition, selected at random.
Another 300 individuals are randomly selected to receive the
traditional treatment.
